Tom Daley has announced that he is going to have a child with husband Dustin Lance Black. It appears they are to use a surrogate, as the pair posted a photograph of a sonogram on Instagram. The two made a Valentine's announcement, posting on their social media feeds: "HAPPY VALENTINES DAY!" with an accompanying image of the baby scan. The Olympic diver, 23, and the director, 43, became engaged in October 2015 and were married last May. They met at an industry event, when Tom made the first move by typing his mobile phone number into the Oscar-winning director's phone, with an invitation to call him. A very happy #ValentinesDay from ours to yours. ������❤️ pic.twitter.com/6ugN3Ho6y3— Dustin Lance Black (@DLanceBlack) February 14, 2018 The pair have wanted a family since they met; Mr Black told OUT Magazine in 2016: "We were so busy making all these plans – we both wanted to have children; we both wanted to build a home of our own someday. I draw, so I was sketching little plans for houses on cliffs overlooking oceans, while Tom watched over my shoulder – it was a very grown-up version of playing house. "Marriage is the foundation to all of these other big plans we have. So we knew we were going to get engaged—it was just a matter of when, and who does it." HAPPY VALENTINES DAY! ❤️������❤️ A post shared by Tom Daley (@tomdaley) on Feb 14, 2018 at 5:44am PST Last year, they tied the knot in an intimate ceremony at a lavish golf resort in Dartmoor national park. Mr Daley wrote: "05.06.17 the day I married the love of my life shared with 120 of our closest family and friends from Texarkana to Plymouth". Mr Daley, 22, was said to have re-enacted the balcony scene from Shakespeare's Romeo and Juliet, calling Black, who is 20 years his senior, his Romeo. A spokesperson said: "Tom and Dustin are thrilled to share that they are expecting their first child in 2018."
